IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1

IBM JDK 1.4.2: removing the -Xnoclassgc argument

If an older version of the data collector (prior to 6.1 fix pack 1 6.1.0-TIV-ITCAMfWAS_MP-FP0001) was earlier configured for this application server instance, the -Xnoclassgc JVM parameter may be present, as that version required it. Remove this argument, as its presence may lead to a slowdown in performance.

Perform the following procedure:

  1. Log into the WAS administrative console for the instance of the application server being monitored by the data collector.

  2. Click Server > Application Servers and select the server_name.

  3. In the Configuration tab, navigate to Server Infrastructure > Java and Process Management > Process Definition > Additional Properties: Java Virtual Machine.

  4. If -Xnoclassgc is still specified in the Generic JVM arguments, remove the setting.

  5. Click Apply.

  6. In the Messages dialog box, click Save.

  7. In the Save to Master Configuration dialog box:

    • If you are under a Network Deployment environment, be sure the check box Synchronize changes with Nodes is selected and then click Save.

    • If you are not under a Network Deployment environment, click Save.
